About Product

Tatcha The Silk Serum 30mL

The Tatcha The Silk Serum is a daily smoothing serum designed to refine the appearance of skin texture for a sleek, smooth and luminous-looking complexion.

Its multi-dimensional approach focuses on factors that can disrupt the look and feel of refined skin texture, including visible pores, accumulated dead surface skin cells, dryness and roughness caused by dryness. At the same time, the formula supports moisture retention, a resilient skin barrier and a firmer, more supple appearance.

At the heart of the formula is Tatcha’s Vital Botanical Blend, combining Cranberry Fruit Extract and Sea Fennel Extract, alongside conditioning Silk Extracts, moisturising Akoya Pearl-derived Extract and the signature fermented HADASEI-3™ complex.

Designed to deliver effective texture care while remaining gentle enough for everyday use, The Silk Serum can be incorporated into both morning and evening skincare routines.

Refines the Look of Skin Texture

Beautifully refined skin texture can make pores and surface roughness appear less noticeable while allowing light to reflect more evenly across the complexion.

The Silk Serum focuses on maintaining this smooth, refined appearance by addressing several concerns that can disrupt the look of skin texture.

These include dryness, accumulated dead surface skin cells, visible pores and roughness associated with dryness.

As the complexion becomes better moisturised and smoother, it reflects light more evenly, contributing to greater radiance and translucent-looking clarity.

Here, translucency refers specifically to the bright, clear-looking appearance created through moisturising care.

Vital Botanical Blend

A key feature of The Silk Serum is Tatcha’s proprietary Vital Botanical Blend, which combines two plant-derived conditioning ingredients.

Cranberry Fruit Extract

Cranberry Fruit Extract provides conditioning care and forms one half of the botanical blend.

Sea Fennel Extract

Crithmum Maritimum Extract, also known as Sea Fennel Extract, complements Cranberry Fruit Extract as a conditioning ingredient.

Together, Tatcha describes these ingredients as supporting the skin’s natural conditioning process—specifically by helping make accumulated dead surface skin cells easier to remove.

This contributes to smoother, more refined-looking skin while supporting a firmer appearance.

Silk Extracts for Smooth, Refined Skin

The Silk Serum contains two silk-derived conditioning ingredients:

• Sericin
• Hydrolysed Silk

Extracted from natural silk, these ingredients are rich in amino acids and are described by Tatcha as having an affinity with the skin.

They help condition and protect skin that can become moisture-depleted, supporting moisture retention and a smoother, more refined skin feel.

The result is skin that feels supple and appears polished without relying on aggressive exfoliation.

Akoya Pearl-Derived Extract

The formula also contains Hydrolysed Conchiolin, a moisturising ingredient derived from domestically sourced Akoya pearl oysters.

Tatcha describes this extract as having similarities to the structure of the skin’s natural moisturising factors, or NMF.

It provides moisture while helping care for the appearance of cloudiness associated with dryness, contributing to a complexion that appears clearer, more luminous and resilient.

Its role in the formula is moisturising rather than whitening or changing the skin’s natural colour.

Powered by HADASEI-3™

The Silk Serum features Tatcha’s signature HADASEI-3™, created through a two-stage fermentation process using ingredients inspired by Japanese food traditions.

Akita Rice

The complex features rice ferment derived from Akitakomachi rice from Akita.

Uji Green Tea

Green tea from Uji contributes to the moisturising complex.

Okinawa Seaweed

Okinawan seaweed completes the trio.

The resulting HADASEI-3™ contains components including naturally occurring amino acids and lactic acid, helping maintain moisture throughout the stratum corneum and support continuously hydrated-feeling skin.

The ingredients identified in the supplied product information are:

• Saccharomyces/Rice Ferment Filtrate
• Camellia Sinensis Leaf Extract
• Okinawa Mozuku Seaweed Extract

All are included for moisturising care.

Supports Firmness & Moisture Retention

The Silk Serum takes a broader approach to skin texture than simply smoothing the surface.

Its combination of botanical extracts, silk-derived ingredients, Akoya Pearl-derived Extract and HADASEI-3™ helps support:

Firmness: Moisturised, well-conditioned skin appears more supple and resilient.

Moisture retention: The formula helps maintain hydration in skin prone to moisture loss.

Barrier function: Supporting comfortable hydration helps maintain the skin’s moisture barrier.

Smoothness: Conditioning and moisturising care helps reduce the appearance and feel of roughness associated with dryness.

Together, these benefits contribute to the serum’s goal of creating a smooth, glossy and refined-looking complexion.

Gentle Daily Texture Care

The Silk Serum is designed to provide texture-refining care without requiring an aggressive skincare approach.

Tatcha describes the serum as low-irritation while still providing effective care, allowing it to be incorporated into everyday skincare morning and evening.

The supplied product information does not identify conventional retinoids or exfoliating acids as the central mechanism of the serum. Instead, its approach focuses on botanical conditioning ingredients, silk components, fermented moisturising ingredients and support for the removal of accumulated dead surface skin cells.

Suitable For

The Silk Serum is particularly relevant for those concerned about:

• Uneven or rough-feeling skin texture
• Visible pores
• Accumulated dead surface skin cells
• Dryness
• Roughness caused by dryness
• Loss of suppleness
• Dullness or cloudiness associated with dryness
• Maintaining moisture and barrier function
• Achieving smoother, more luminous-looking skin
• Daily texture care without an aggressive-feeling routine

Texture & Finish

The Silk Serum is designed to blend smoothly into the complexion as part of a daily skincare routine.

With continued moisturising and conditioning care, it helps skin feel sleek, smooth and refined, while improved hydration contributes to a glossy, translucent-looking finish.

The supplied product information does not provide a specific texture classification such as gel, oil or emulsion, so no additional texture claims have been added.
